5.3 NTEP Sealing and Operation
The balance is sealed by threading a wire through two tabs on the bottom front of the scale (see below-right image). One tab is
part of the top half of the enclosure and the other is part of the bottom half. There is also a flat plastic plug that covers a hole on
the bottom front of the balance which is sealed with a tamper-evident seal. If the plug is removed, a small switch can be
accessed to toggle between NTEP and non-NTEP modes.
When in NTEP mode, an outline of the least significant digit appears on the display as shown in the image below with digit 3.
NTEP mode does not allow access to the calibration mode.
Depending on capacity, there are two ways to seal the TP Series.

balance, the lead
seal would be
placed here.

seal and plug deny
